Abstract (en)
[origin: WO9313385A2] Vehicle navigation apparatus (10) calculates an initial route to a destination (52) via connected road segments (55, 59) defined in a road map data base. In response to a can't do-reroute signal, indicative of the vehicle user determining unsuitability of following the initial route guidance instructions, a new route (55, 60, 61, 62, 59) to the destination is provided. Automatically excluded from the new route is a maneuver (ordered road segment pair (55-59)) and/or a road segment of the initial route. This prevents the new route from including an initial guidance instruction which was determined as unsuitable. Also, calculated routes are provided by calculating the route from a predicated position of the vehicle at a subsequent time based on the vehicle's current position, direction and rate of travel. This ensures that when the route is provided at the subsequent time, the vehicle will not have passed the first maneuver to be implemented in the calculated route.
